Using the predictability criterion for selecting extended verbs for Shona dictionaries

The paper examines the "predictability criterion", a classificatory tool which is used in selecting affixed word forms for dictionary entries. It focuses on the criterion as it has been used by the African Languages Lexical (ALLEX) Project for selecting extended verbs to enter as headwords in the Project's first monolingual Shona dictionary Duramazwi ReChiShona. The article also examines the status of Shona verbal extensions in terms of their semantic input to the verb stems they are attached to. The paper was originally motivated by two observations: (a) that predictability seems to be a matter of degree; and (b) that the predictability criterion tended to be used inconsistently in the selection of extended verbs and senses for Duramazwi ReChiShona. An analysis of 412 productively extended verbs that were entered as headwords in Duramazwi ReChiShona shows that verbal extensions can bring both predictable and unpredictable senses to the verb stems they are attached to. The paper demonstrates that for an effective use of the predictability criterion for selecting extended verbs for Shona dictionaries, there is need for the lexicographer to have an in-depth understanding of the kinds of semantic movements that are caused when verb stems are extended. It shows the need to view verbal extensions in Shona as derivational morphemes, not inflectional morphemes as some earlier scholars have concluded.Keywords: definition; derivational morpheme; dictionary; dictionary entry; lexeme; lexicography; morphology; predictability criterion; semantics; shona; verb stem; verbal extension

Linguistic variation in Shona with special reference to monolingual dictionaries*

This article focuses on the problems lexicographers of monolingual dictionaries face when dealing with a language characterised by differences associated with geographical variation. The article specifically seeks to explore problems with which Shona lexicographers are confronted when working on monolingual Shona dictionaries. It does so by looking at some lexicographic aspects such as tone marking, sense ordering and treatment of synonyms and variants. Linguistic variation has always been a problem for writers of reference works, especially those normative in nature and function. The challenge is that of representativeness, that is, the production of a work which incorporates all the information it is supposed to provide. If the work fails to represent the language of the total population it is assumed to cover, then it is prone to criticism, usually by those whose dialect is not well represented. The article contains the writer's experience in the Afri-can Languages Lexical (ALLEX) Project, at present the African Languages Research Institute (ALRI). The ALRI, accommodated at the University of Zimbabwe, has the compilation of monolin-gual dictionaries for the indigenous languages of Zimbabwe as one of its major objectives. Al-though illustrative examples are drawn from Shona alone, it is, however, believed that the prob-lems highlighted in this article may not be peculiar to Shona, but can also apply to other Bantu and world languages. Keywords: allex project, alri, corpus, dialect, monolingual lexicogra-phy, shona, subdialect, synonym, tone, variant, variatio

To Call or Not to Call a Spade a Spade: The Dilemma of Treating 'Offensive' Terms in "Duramazwi Guru reChiShona*"

As noted by Béjoint (2000: 6), the main objective in dictionary-making is to define words and terms. This is especially the case if the fact is accepted that dictionaries are mostly con-sulted for word meaning and that, in the consultation process, the user hopes to acquire and/or verify certain information. However, as again noted by Jackson (1988), Landau (1984), Svénsen (1993) and Zgusta (1971), among others, the description of word meaning is one of the greatest difficulties with which the lexicographer has to cope. This article discusses some of the challenges facing lexicographers when defining 'offensive' headwords in a monolingual dictionary. It is based on experiences of defining such headwords for the general-purpose, medium-sized, synchronic, monolingual Shona dictionary, Duramazwi Guru reChiShona (henceforth DGC) (Chimhundu et al. 2001). DGC was compiled and edited by a six-member team of mother-tongue speakers of Shona who are researchers at the African Languages Research Institute (ALRI). The article also discusses some of the strategies the team of editors adopted as ways of dealing with offensive words in DGC. One such strategy is the use of euphemism in defining.

The utilisation of outer texts in the practical lexicography of African languages

In this article, an analysis of the utilisation of outer texts in recently compiled dictionaries of African languages is presented. The analysis is undertaken in the context of an upsurge of the compilation of dictionaries in the African languages. It is undertaken with a view to do a qualitative evaluation of the many new dictionaries of African languages that have come on the market in recent years. The point of departure is that prior to the recent lexicographic developments, the then available dictionaries were compiled in the context of the limited role the African languages played. It has been found that most of those dictionaries are limited in scope, perspective and function and hence less effective now that the languages are being assigned a greater social role. The evaluation of outer texts in modern dictionaries is therefore a way of measuring the extent to which lexicographic practice in the African languages is applying theoretical developments to produce better dictionaries

John 8:3–11 and gender-based violence in Johane Marange Apostolic Church, Ruwa District, Zimbabwe

DATA AVAILABILITY : Data sharing is not applicable to this article as no new data were created or analysed in this study.Special Collection : Africa Platform for NT Scholars, sub-edited by Ernest van Eck (University of Toronto, Canada).The authors are participating in the research project ‘Africa Platform for NT Scholars’, directed by Prof. Dr Ernest van Eck, Department of New Testament and Related Literature, Faculty of Theology and Religion, University of Pretoria.John 8:3–11 depicts the story of a woman who is condemned to death because she was caught in the act of adultery. The Pharisees and Scribes who condemned the woman cited Deuteronomy 22:23–24 and Leviticus 20:10 which prescribe death penalty for adultery. What begs answers through this hermeneutical study of the pericope from the lens of genderbased violence (GBV) in Johane Marange Apostolic Church, Ruwa District, in Zimbabwe, is why only the woman was picked for condemnation yet the cited Mosaic Law provides that both the man and the woman who engage in the act of adultery face capital punishment. The article interrogates the text to identify limbs or tentacles on which the decision by the Pharisees and Scribes to condemn only the woman leaving out the man stands. An exegetical study of the text is conducted to explore possible reasons behind the relegation of women to the receiving end of misogynistic socially constructed gender stereotypes. A qualitative methodological praxis fusing socio-historical method and qualitative analysis is engaged in analysing the Biblical Johannine and Johane Marange Apostolic Church Ruwa District communities, respectively. The article mirrors patriarchal tendencies in the Johane Marange Apostolic Church into the selective application of biblical doctrine between males and females depicted in the Johannine text of John 8:3–11. The article argues and concludes that, as reflected in John 8:3–11, GBV practices in Johane Marange Apostolic Church have sentenced women to sexual exploitation, rape, early child marriages and high maternal mortality rate. CONTRIBUTION : The study recommends ways of cutting the tentacles of the acts of GBV being imposed on women in general, and on the girl child in particular.http://www.hts.org.zaam2024New Testament StudiesSDG-05:Gender equalit

Paul, the prisoner (Acts 23:34-35) : an insight into 2018-2022 political prisoner’s rights in Zimbabwe

DATA AVAILABILITY : Data sharing is not applicable to this article as no new data were created or analysed in this study.This research is part of the research project, ‘Biblical Theology and Hermeneutics’, directed by Prof. Dr Andries van Aarde, Post Retirement Professor and Senior Research Fellow in the Dean’s Office, Faculty of Theology and Religion, University of Pretoria.Special Collection: The contextual reading of the New Testament in the socio-politicaUndisputed letters of Paul and Acts of the Apostles are replete with details of the Gentile Missionary’s multiple imprisonments, so much as to qualify him a ‘jailbird’ description. Paul’s incarceration in Herod’s palace for 2 years (Ac 23:34–35), his arraignment before Governor Felix and subsequent detention for 5 days before plea (Acts 24) on charges of inciting public violence, being a ringleader of a cultic faction and causing disturbances in the Jerusalem Temple, resonate with the contentious arrests and imprisonment without bail and trial of members of opposition political parties in Zimbabwe. Consistent with New Testament passages that exhort caring for prisoners and the need to grant justice to those facing trial, this study seeks to understand how inmates in Zimbabwean prisons have been on the receiving end of relics of the ancient Roman Legal system in the country’s Human Rights history between 2018 and 2022. The article demonstrates how the New Testament can be deployed to grapple with distress calls emerging from Zimbabwe’s prison walls as part of advocacy for judicial reforms in the country’s quest for rule of Law. At the end, the article recommends ways in which Churches in Zimbabwe can tap from New Testament passages how to operate an effective prison ministry in liaison with the Prisons and Correctional Services Department of the Government of Zimbabwe. The article employs qualitative methods of Socio-Historical and Ethnographic Analyses to discuss how human rights pitfalls in Paul’s imprisonments present remedial lessons in Zimbabwe’s quest for judicial reforms.

Demonstration of how Early Christian Literature can dialogue with contemporary African Sitz im Leben for social transformation.http://www.hts.org.zaam2024New Testament StudiesNon

Higher order modulation formats for high speed optical communication systems with digital signal processing aided receiver

The drastic increase in the number of internet users and the general convergence of all other communication systems into an optical system have brought a sharp rise in demand for bandwidth and calls for high capacity transmission networks. Large unamplified transmission reach is another contributor in reducing deployment costs of an optical communication system. Spectrally efficient modulation formats are suggested as a solution to overcome the problems associated with limited channels and bandwidth of dense wavelength division multiplexing (DWDM) optical communication systems. Higher order modulation formats which are considered to be spectrally efficient and can increase the transmission capacity by transmitting more information in the amplitude, phase, polarization or a combination of all was studied. Different detection technologies are to be implemented to suit a particular higher order modulation format. In this research multilevel modulation formats, different detection technologies and a digital signal processing aided receiver were studied in a practical optical transmission system. The work in this thesis started with the implementation of the traditional amplitude shift keying (ASK) modulation and a differential phase shift keying (DPSK) modulation systems as they form the basic building block in the design of higher order modulation formats. Results obtained from using virtual photonics instruments (VPI)simulation software, receiver sensitivity for 10Gbpsnon-return-to-zero (NRZ), amplitude phase shift keying (ASK) and DPSK signals were measured to be -22.7 dBm and -22.0 dBm respectively. Performance comparison for the two modulation formats were done over different transmission distances. ASK also known as On-Off keying (OOK) performed better for shorter lengths whereas DPSK performed better for longer lengths of up to90km.Experimental results on a 10 Gbps NRZ- ASK signal gave a receiver sensitivity of -21.1 dBm from digital signal processing (DSP) aided receiver against -19.8 dBm from the commercial bit error ratio tester (BERT) yielding a small difference of 1.3 dB hence validating the reliability and accuracy of the digital signal processing (DSP) assisted receiver. Traditional direct detection scheme and coherent detection scheme performances were evaluated again on a 10 Gbps NRZ ASK signal. Coherent detection that can achieve a large unamplified transmission reach and has a higher passive optical splitting ratio was first evaluated using the VPI simulation software. Simulation results gave a receiver sensitivity of -30.4 dBm forcoherent detection and -18.3 dBm for direct detection, yielding a gain in receiver sensitivity of 12.1 dB. The complex coherently detected signal, from the experimental setup gave a receiver sensitivity of -20.6 dBm with a gain in receiver sensitivity of 3.5 dBm with respect to direct detection. A multilevel pulse amplitude modulation (4-PAM) that doubles the data rate per channel from10 Gbps to 20 Gbps by transmitting more information in the amplitude of the carrier signal was implemented. This was achieved by modulating the optical amplitude with an electrical four level amplitude shift keyed (ASK) signal. A receiver consisting of a single photodiode, three decision circuits and a decoding logic circuit was used to receive and extract the original transmitted data. A DSP aided receiver was used to evaluate the link performance. A receiver sensitivity of -12.8 dBm is attained with a dispersion penalty of about 7.2 dB after transmission through 25 km of G.652 fibre

Sample Size Calculations for Population Size Estimation Studies Using Multiplier Methods With Respondent-Driven Sampling Surveys.

BACKGROUND: While guidance exists for obtaining population size estimates using multiplier methods with respondent-driven sampling surveys, we lack specific guidance for making sample size decisions. OBJECTIVE: To guide the design of multiplier method population size estimation studies using respondent-driven sampling surveys to reduce the random error around the estimate obtained. METHODS: The population size estimate is obtained by dividing the number of individuals receiving a service or the number of unique objects distributed (M) by the proportion of individuals in a representative survey who report receipt of the service or object (P). We have developed an approach to sample size calculation, interpreting methods to estimate the variance around estimates obtained using multiplier methods in conjunction with research into design effects and respondent-driven sampling. We describe an application to estimate the number of female sex workers in Harare, Zimbabwe. RESULTS: There is high variance in estimates. Random error around the size estimate reflects uncertainty from M and P, particularly when the estimate of P in the respondent-driven sampling survey is low. As expected, sample size requirements are higher when the design effect of the survey is assumed to be greater. CONCLUSIONS: We suggest a method for investigating the effects of sample size on the precision of a population size estimate obtained using multipler methods and respondent-driven sampling. Uncertainty in the size estimate is high, particularly when P is small, so balancing against other potential sources of bias, we advise researchers to consider longer service attendance reference periods and to distribute more unique objects, which is likely to result in a higher estimate of P in the respondent-driven sampling survey
